Development of test capabilities in liquid and gasous ammonia and cryogenic temperatures at the French Corrosion Institute – Saint Etienne Site. Several jacketed autoclaves and test cells are available for specimens exposure in liquid amonia below -35°C. Gas NH3 gas permeability at low temperature is also possible. The comissionning of a new test room for ammonia testing is ongoing.

Commissioning of a new test room dedicated to material testing under hydrogen pressure at The French Corrosion Institute – Saint-Etienne site. New equipments have been invested to extend the pressure range we can investigate, to allow for testing in contaminated gas (mainly in presence of H2S) and offer new test methods applicable in research projects and consultencies. Several test frames are now available : o Several autoclaves for batch exposures up to 300°C/300 bar. o Two test frames for fracture toughness and fatigue crack growth. rate evaluations up to 700 bar and -150/180°C. o Several permeation test cells up to 400 bar. o One test frame for slow strain rate and Ripple load test up to 185 bar. o Cryogenic test using hollow specimens down to -150°C. o Thermodesorption spectroscopy.…

The French Corrosion Institute continues developing R&D and test services for material resistance evaluation under gaseous hydrogen pressure. In addition to our standard test capabilities, we can also adapt to specific requirements and develop “on-demand” test method. In this example, we have produced for one of our client, a “fit-for-purpose” test bench capable to simulate the exposure of tubing to pressure cycles of several tens of bar of hydrogen. The equipment is operated to mimic the real pressure cycle to which the part will be exposed in service. The number of cycles is defined to simulate the full life time of the product and ensure its integrity in service.

The French Corrosion Institute and RISE together with the Member Research Consortium ‘Corrosion Properties of Coil-coated Products’ are organizing the 5th International Symposium ' Corrosion of Prepainted Materials’. It will be held on May 31st, 2023 in the beautiful city of Stockholm (Sweden) in Van Den Nootska Palatset. The symposium will feature presentations by selected speakers that cover the following topics: Surface and Adhesion properties, Advanced techniques, Performance of prepainted materials, Mechanisms...

The site of Saint-Etienne is currently modifying its capabilities to allow test under H2 pressure.Experiments under static (constant load, permeation) and dynamic loading (Slow Strain Rate Test, Incremental Step loading) were already succesfully implemented up to 100 bar 

In the frame of a projects leaded by CETIM (French R&D Center for Mechanical Industries) and after long-term collaborations with Institut de la Corrosion, new very high-pressure capabilities (up to 1000 bar) have been implemented at Saint-Etienne - Total surface 50 m² / 6 autoclaves - Dedicated for a specific project at least during the period 2019-2021 - Probably open to other consultencies from 2022
